A man has denied the murder of Pc Keith Blakelock, who died during the Broadwater Farm riots in 1985.

Nicholas Jacobs, 45, is accused of killing the 40-year-old officer, who was stabbed as he tried to protect firefighters tackling a blaze at a supermarket at the height of the unrest in Tottenham, north London.

Jacobs looked straight in front of him as he spoke the words "not guilty" at the Old Bailey.
